Building reliable software and the platforms that run it.

Denis Tita · Software Engineer & DevSecOps Engineer

I build reliable software and secure cloud platforms across the full delivery lifecycle—from C#/.NET applications to AWS infrastructure, Kubernetes, GitOps, CI/CD, observability, and Zero Trust.

ABOUT

Engineering software and platforms end to end.

I am a Software Engineer and DevSecOps Engineer with more than five years of experience building enterprise applications, secure cloud platforms, and AI-enabled solutions.

My background combines full-stack software development with cloud infrastructure, platform engineering, and applied AI. I build backend and enterprise applications with C#, .NET, ASP.NET Core, Entity Framework Core, Blazor, REST APIs, and SQL, while also building AI-powered applications using Python, OpenAI, RAG, vector search, and semantic retrieval.

My cloud and DevSecOps experience includes AWS, Terraform, Kubernetes, Amazon EKS, Docker, Helm, Kustomize, Argo CD, CI/CD, observability, RBAC, OPA, Keycloak, Envoy Gateway, STIG-aligned environments, and Zero Trust security patterns.
